From 18 August at 0h35 UTC, the thermal camera of Punta Dei Corvi / on Stromboli, shows the resumption of effusive activity by a probably ephemeral vent at altitude 550-600 meters, above the area of ​​the central crater . The products issued roll along the Sciara del Fuoco.

A Modis image at 1:50 UTC records a thermal anomaly of 125 MW to 148 MW, compatible with this activity.

The explosive activity continues without significant modification.

A small emission of ash has been reported for a few days at Asosan, on the Japanese island of Kyushu.

On August 19th, black and fluffy ashes accumulate little by little, in the absence of precipitation.
